![]() 173 forum posts 8 photos | I'm making a Quorn type grinder (actually a Bonelle) and cannot find one vital piece of information: How much lubricant do you need in the spindle? I assume oil is introduced via the 2ba hole about half way along the spindle housing but how much? One drop? A teaspoon full? or enough to flood out of both ends via the bearing caps? Is there a builder or owner out there who can guide me. Thanks. Edited By Bizibilder on 07/05/2019 18:18:56 |

![]() 814 forum posts 36 photos | I built my Quorn many years ago and think the book does mention something about lubrication if my memory serves me correctly. I think it needs a small amount of oil and to be honest I think I just put a little oil on the bearings during assembly and have never added any since over the last twenty years or so (perhaps I should ).

![]() 173 forum posts 8 photos | Thanks. Every twenty years it is - should be around long enough for the first re-oiling but i'd have to be well over 100 to make it to the second!! Edited By Bizibilder on 07/05/2019 19:39:40 Edited By Bizibilder on 07/05/2019 19:41:26 |

![]() 431 forum posts 252 photos | There was an article in MEW # 62 "Compendium of the Quorn" pg 20,21 that covered the amount of oil to use in the spindle,including the calculations to determine the volume of oil required. This is what I used when I made my spindle and it has been perfectly satisfactory. If you can't find the article send me a PM. John Edited By John Purdy on 08/05/2019 18:27:33 |

![]() 173 forum posts 8 photos | Lots of heavy boxes needed to be moved but I now have those issues of MEW (MEW 62 and 63)- Thank you that is about the most comprehensive review of the Quorn and all the associated articles and literature that I have seen. Not sure how i missed it when searching but I did! Thank you John. |

![]() 431 forum posts 252 photos | Further to my last, using the method in the article I calculated that the quantity of oil that I needed was 2.2cc. When I built my spindle I used a stack of 4 Belleville springs instead of the coil springs and spring box that Chaddock used, so if made to the original drawings the quantity would probably be slightly different. Glad I could be of some help. John |

1 forum posts | I lubricated my Quorn spindle bearings with Kluber Iso Flex Super Tel. If it’s good enough for a Deckel pantograph spindle, Deckel mill spindle, and Aciera mill spindle, it’s good enough for a Quorn. The speed is well within acceptable range for this grease. I think there’s less risk of contamination using grease, because one packing should last a decade. |
